Retrospective review of 46 hips in 45 patients undergoing revision THA via extended slide trochanteric osteotomy (1991–1996), assessing union rate, time to union, and whether fixation variables or bone quality predict healing outcomes.
When facing a complex revision THA requiring removal of well-fixed distal cement, an extensively coated cementless stem, or proximal femoral deformity, the extended slide trochanteric osteotomy offers reliable healing (~98% union) by preserving the abductor-vastus sling.
Reserve cortical strut augmentation for cases with genuinely poor bone apposition — adding it routinely delays union without improving the rate.
